Confused!!

So last week I took a test 4 days before my missed period and it was faint positive.. and my period was de November 5th never comes early normally sometimes late anyways on the 4th I started bleeding heavy and I bled heavy for two days mind you my period is always super heavy until the day I get off they normally last 6-7 days. Well anyways I bled heavy for 2 days and now it’s really light I’m confused on what’s going on.. I had a miscarriage and may in bled heavy heavy for 6 days straight. Anybody have any idea what’s going on?
